Abstract

The rotor comprises a ceramic wheel 14 having an inner row of turbine blades 16 and an outer row of compressor blades 18 separated by a mid-blade shroud 20, and an outer shroud 22 filament wound with a composite so as to form a hoop 24 providing compression loading of the ceramic components during rotation. The wheel 14 has a ceramic or metallic hub 12 for attachment to a shaft.
